METHOD OF MAKING REENFORCED MATTRESSES Filed Jan. 1B, 1928 Patented Feb. 21, 1933 UNITED stares narrar orifice EDWARD ROBERTI, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TOYvROBERTI BROS., .A CORPORATION OF CALIFORNIA METHOD OF MAKING REENFORCE-ID` MATTRESSES .Application led January 18, 192,8. Serial No. 247,547.

My invention relates to the art of making mattresses, being more particularly a mattress construction in which provision is made for reenforcing the mattress against the boxinG. f

Mattresses, as ordinarily constructed, have a tendency to flatten along the boxing or side portions oi' the mattress, due largely to the fact that the filler works away from the boxing, and it is one of the principal objects of my invention to produce a mattress of simple form and construction, in which provision is made vfor reeniiorcingl the boxing, and at the same time compact the lillcr and retain the same along the sides of the mattress.

Another object ot my invention is to nroduce a mattress of the class described, wherein concealed means are employed tor compacting the filler around the sides ot the mattress.

Other objects and advantages will appear hereinafter from the following description and drawing.

Referring to the drawing, which is i'or illustrative purposes only,

Fig. 1 is a diagrammatic plan View of a mattress embodying a form ot my invention.

Fig. 2 is a side view of the mattress shown in Fig. 1.

Fig. 3 is an enlarged sectional View on line 3-3 of Fig. 1, showing the needle employed during the stitching operation.

Fig. 4 is a sectional view on line 4,-4 of Fig. 3.

Fig. 5 is a sectional View similar to Fig. il, showing a modified form of my invention, and y Fig. 6 is a side View of the mattress shown in Fig. 5.

More particularly describing the embodiment of my invention shown in Figs. 1 to 4, inclusive, 10 designates a mattress which may be made in any well known manner, 11

and 12 designating upper and lower ticlrmembers respectively, and 13 the boxing or side member of the tick, the tick members being connected to the boxing by rolled edges indicated at 14.

The mattress in the form shown is of the tufted type, tufts being indicated at 15, such tufts vbeing formed by concealed ties 16, which engage tabs 11T and 18, secured to lreenforci-ng strips 19 and 20', stitched to the respective tick members 11 'and 12', the ties being inserted Vthrough eyelets 22.

In the preferred embodiment of my invention, I secure, in any well known manner, a plurality of eyelets 24 in the boxing .13, and behind such 'eyelets on the inside ot the boxing I providea strip or foundation secured to the boxing by two rows 'of stitching, one above and one below the eyelets. The strip 25 reentorces the boxing and provides an anchor or base for a compacting member 2G.

The compacting or reentorcing member 26 consists or" a continuous piece of' twine which is sewn through the strip 25 and the filler 27 in the following manner. A needle N is used, the twine 2li being threaded in the needle andthe threaded needle passed through an eyelet 24 and strip 25 angularly, both laterally and upwardly, until the needle is passed through the tick member 11 a suilicient distance to be grasped by the hand of the operator, but not a suiiicient distance for the thread or twine to pass through the tick member, `the needle then being turned so as to point downwardly and laterally toward the next eyelet and pushed back so that the thread or twine is passed through the strip 25 and the eyelet. This operation is repeated, one end of each stitch formed by the twine engaging the strip 25, as indicated at 30, and the other end 31 of each stitch engaging the filler so that the intervening filler is held in compact relation against the boxing.

The stitching operation is repeated until a series of V-shaped stitches are formed around .the sides of the mattress, as indicate-d in By drawing the iiller into compact form around the boxing, as above described, the sides of the bed are firm and retain their shape.

hile I have shown and described an eyelet construction, in combination with a strip on the inside oil`: the boxing', it is to be understood that my invention is not limited to this concealed type of articie, but includes any form oi construction in which the .iiller is held in compaxft relation with the boxing` by means oi: twine or thread, either directly or indirectly engaging the boxing'.

I Claim as my invention: y

l. The method ot nnikingf a mattress consist-infy of tici; members, a boxing and iiller therein, which comprises, 'forming a series ot openings in said honing', stitching a strip ot fabric to the inside o' the boxing behind said openings, and passing' a threaded needle through one openin` part Way 'hrough the tilier, then outwardly through another opening and inwardly through the same opening, and repeating' such movement ot the threaded needle to form a series of stitches in said fabric strip extending into and engaging the liller.

i2. The method of making a mattress of the tyge in which the mattress consists ot tick members hfivincfg` a filler therebetween and a boxing haif'ing openings therein and a fabric member stitched to the inside thereof behind the openings which comprises passing' a threaded needie through one opening, then outwardly through another opening' and inwardly through the same opening, and repeating' suoli movement of the threaded needle to form a series oit stitches in the fabric member extending into and engaging the iiller.

In testimony uf'hereot, I have hereunto set my hand at Los Angeles, California, this 12th day of January. 1928.
